nongroove electric knife gate valve

电动刀闸阀铸铁阀体采用整体式结构刀闸阀,包括阀体,闸板和U型密封条,阀体中腔底部设有凹槽并装有弹性U型密封条,当阀门关闭时闸板下移,闸板底部边缘与密封条接触进而压缩密封条进入凹槽中实现阀体和闸板的密封;当刀闸阀开启时闸板上移,闸板底部边缘与密封条脱离,密封条弹起与凹槽平整,能防止刀闸阀在使用过程中,介质沉淀物积存在阀体中腔的凹槽里，不易堵塞、无残留，管道清洗方便，从而有效提高刀闸阀的密封效果,防止阀门关闭时泄漏。使用寿命更长，维护更简单；法兰密封面镶O型圈，无须另配法兰垫片，安装简单方便，磨擦系数小，启闭灵活，该系列刀闸阀可配电动可通过现场控制箱、现场电装按钮、远程PLC电动智能控制等附件可以完成开、关和调试的动作的自动控制。用户可根据实际需要进行选择。

Cast Iron , with the overall structure,electric knife gate valve includes body,disc and U-seal, groove and flexible U-seal at the bottom of the cavity. Disc is moved down when valve is closed, the bottom edge of disc meets with the seal and then compresses into the groove to achieve sealing . Disc is moved up when knife gate valve is opened, the bottom edge of disc breaks from seal,

 Seal bounces up with groove formation to prevent media accumulated in the body cavity , not blocked easily and residue, pipe is cleaned easily ,and to prevent leakage when knife gate valve is closed .That improves knife gate valve's sealing effect effectively . With longer service life, simply maintenance ,flange O-ring sealing , without changing flange gasket,simply installation and small friction coefficient ,flexibly opening and closing, the series knife gate valve can be equipped with electric and controlled through on-site boxes, on-site Denso button and remote PLC inligent to achieve open and close. Users can choose based on themselves needs.
